摘要
目的探讨短暂性脑缺血发作(TIA)患者颅内外血管病变。方法对45例患者进行头颈64排CT血管造影(CTA)及经颅多普勒(TCD)和颈动脉彩超检查,观察其异常情况。结果 CTA检查45例TIA患者中40例颅内外共116支动脉狭窄或闭塞,总异常率为88.9%,颅内动脉狭窄或闭塞61.1%高于颅外动脉38.9%,颅外动脉狭窄中以颈内动脉(ICA)颅外段狭窄最多44.4%,颅内动脉狭窄中以ICA颅内段狭窄最多32.3%,频发(发作频率≥2/d)及短时程(发作持续时间在1 h以内)患者重度狭窄及闭塞发生率(74.2%)高于非频发组及长时程(发作持续时间≥1 h),均P<0.05,有统计学意义;TCD异常75.6%,占CTA异常的94.4%,TCD血流速度增快85支,较CTA65支多;颈动脉超声检查结果16例颈部动脉狭窄或闭塞,共35支动脉狭窄或闭塞,其中椎动脉狭窄或闭塞7支。彩色多普勒超声检查对颈动脉狭窄或闭塞检出率低于CTA,对椎动脉的狭窄或闭塞检出率远低于CTA。结论 TIA患者颅内外动脉狭窄或闭塞及斑块发生率高,CTA检查显示动脉狭窄或闭塞异常率为88.9%,颅内动脉狭窄或闭塞高于颅外动脉,频发及短时程患者重度狭窄及闭塞发生率高于非频发组,有统计学意义。
【Objective】 To explore TIA patients intracranial or extracranial blood vessel lesion.【Methods】 Examined 64-slice spiral CT angiography（CTA）,Transcranial Doppler（TCD） and color Ultrasonography in the 45 TIA patients,observed the anomal conditions.【Results】 In the 45 TIA patients with examined 64-slice spiral CT angiography（CTA）,there are 40 cases of patients and 116 blood vessels with intracranial or extracranial angiostenosis or obstruction.Abnormal rate is 88.9%.The patients of intracranial angiostenosis or obstruction（61.1%） are higher than patients of extracranial angiostenosis or obstruction（38.9%）.The patients of extracranial internal carotid are the most in the patients of extracranial angiostenosis（44.4%）,however,the patients of intracranial internal carotid are the most in the patients of intracranial angiostenosis（32.3%）.Incidence rate（74.2%） of serious angiostenosis or obstruction patients with frequency（≥2/d） and short time（≤1 h） is higher than the patients with infrequent and long time（1 h）.The difference of the two groups is statistically significant（P 0.05）.Abnormal blood vessels examined patients with TCD（75.6%） is 94.4 % of abnormal blood vessels with CTA.85 blood vessels that Blood flow velocity increased examined with TCD are more than 65 blood vessels examined with CTA.Through color Ultrasonography,the results are carotid arteries angiostenosis or obstruction of 16 cases,35 arteries angiostenosis or obstruction,7 vertebral arteries angiostenosis or obstruction.Detection rate of Carotid arteries or vertebral arteries angiostenosis or obstruction with color Ultrasonography is lower than with CTA.【Conclusion】 Incidence rate of TIA patients intracranial or extracranial angiostenosis or obstruction is high.Abnormal rate examined with CTA is 88.9%.Incidence rate of intracranial angiostenosis or obstruction is higher than extracranial angiostenosis or obstruction.Incidence rate of serious angiostenosis or obstruction patients with frequency and short time is higher than the patients with infrequent and long time.The difference of the two groups is statistically significant.
